Final answer:
Fuses are removed during reconnection for safety to prevent shock hazard from charged capacitors. The bleeder resistor must have a high resistance to allow a slow, controlled discharge, resulting in a higher time constant for safe discharging.
Step-by-step explanation:
The removal of the fuse from a capacitor bank control mechanism during reconnection is primarily for safety reasons. In electronic apparatuses with large capacitors, especially those at high voltage, they can retain a charge long after the device is turned off, posing a significant shock hazard. A bleeder resistor is added across the capacitor to safely discharge the stored energy when the apparatus is powered down.
The bleeder resistance must be much greater than the effective resistance of the rest of the circuit. This is because the bleeder resistor is intended to allow for a slow, controlled discharge. If the resistance was low, it would discharge the capacitor too quickly, which could be dangerous and might cause damage to the circuit. A high resistance ensures a slow and safe discharge rate. Consequently, the higher resistance of the bleeder creates a higher time constant for the capacitor's discharge which prolongs the time it takes for the capacitor to be safely discharged to an insignificant voltage.
